Energy-saving and environment-friendly PVC coating heating furnace

Abstract

The invention discloses an energy-saving and environment-friendly PVC coating heating furnace. The heating furnace comprises a combustion chamber, a heating chamber, heating flues and a discharge flue, and is characterized in that a flue gas heat exchanger is arranged on the upper portion of the discharge flue; a cold medium outlet of the flue gas heat exchanger communicates with an inlet of a catalytic combustor through a waste gas pipeline, and a middle section of the waste gas pipeline is arranged in an inner cavity of the combustor; irradiation arc plates and semicircular annular fins are arranged on the side walls, facing the heating flues, of the heating chamber; and a heat accumulating type heat exchanging body is arranged in the flue gas heat exchanger. Compared with the prior art, the energy-saving and environment-friendly PVC coating heating furnace has the following advantages that an organic waste gas treating device is designed, the three processes of air suction, preheating and catalytic combustion are conducted and completed at the same time, waste gas is subjected to double-stage preheating, it is guaranteed that the organic waste gas has an initiation temperature required by catalytic combustion, energy is saved, and environment friendliness is achieved; and the irradiation arc plates of special structures are adopted for the side walls of the heating flues, the combustion chamber and a feedback regulating device are designed, a temperature in the furnace is uniform and stable, it is guaranteed that a mould is uniformly heated, and the yield of products is greatly increased.

Description

technical field [0001] The invention relates to the technical field of molding production equipment, in particular to an energy-saving and environment-friendly molding heating furnace. Background technique [0002] As a traditional PVC molding processing method, dip molding plays an important role in PVC molding processing. Compared with traditional injection molding, extrusion molding and other processing methods, dip molding has the advantages of simple processing technology, short molding cycle, no or small internal stress of the material, and can be manufactured by multiple dip molding techniques. Processing large materials does not require large Equipment and mold investment costs and other advantages. However, because the existing PVC molding equipment lacks the process of dealing with the organic waste gas produced in the PVC plasticization molding process, it cannot be popularized on a large scale. Therefore, it is very necessary to develop an energy-saving and envi...

AI Technical Summary

Problems solved by technology

On the one hand, it is difficult to control the temperature in the PVC molding heating furnace using gas combustion, and the heating of the mold is very uneven, resulting in a high waste rate of plasticized PVC products; on the other hand, the organic waste gas generated during the dipping process It is difficult to deal with, and it is usually emptied directly, which brings serious pollution to the environment
